Exempel på hur man kan använda ETHMOIDAL i en mening

• The maxillary sinuses are located under the eyes; the frontal sinuses are above the eyes; the ethmoidal sinuses are between the eyes and the sphenoidal sinuses are behind the eyes.
• The cribriform plate forms the roof of the nasal cavity and also contributes to formation of the anterior cranial fossa, the ethmoidal labyrinth consists of a large mass on either side of the perpendicular plate, and the perpendicular plate forms the superior two-thirds of the nasal septum.
• The typical snake skull has a solidly ossified braincase, with the separate frontal bones and the united parietal bones extending downward to the basisphenoid, which is large and extends forward into a rostrum extending to the ethmoidal region.
• The superior surface is convex, and marked by depressions for the convolutions of the frontal lobes of the brain, and faint grooves for the meningeal branches of the ethmoidal vessels.
• This is bounded by the uncinate process, medially, the orbital lamina of ethmoid bone (lamina papyracea), laterally, and the ethmoidal bulla, posterosuperiorly.
• In 90% of patients an anterior ethmoidal cell (called the "agger nasi cell") can be found in the lacrimal bone below the agger nasi ridge.
• The ethmoid air cells consist of numerous thin-walled cavities in the ethmoidal labyrinth that represent invaginations of the mucous membrane of the nasal wall into the ethmoid bone.
• It carries sensory branches from the eyes, conjunctiva, lacrimal gland, nasal cavity, frontal sinus, ethmoidal cells, falx cerebri, dura mater in the anterior cranial fossa, superior parts of the tentorium cerebelli, upper eyelid, dorsum of the nose, and anterior part of the scalp.
• Tributaries of the superior ophthalmic vein (may) include: the anterior ethmoidal vein and posterior ethmoidal vein, lacrimal vein, central retinal vein (sometimes), superior vorticose veins, medial palpebral veins, inferior ophthalmic vein (sometimes), and veins from the superior rectus muscle, superior oblique muscle, and medial rectus muscle.
• The semilunar hiatus (eg, hiatus semilunaris) is a crescent-shaped/semicircular/ curved/groove upon the lateral wall of the nasal cavity at the middle nasal meatus just inferior to the ethmoidal bulla.
• The ethmoidal labyrinth or lateral mass of the ethmoid bone consists of a number of thin-walled cellular cavities, the ethmoid air cells, arranged in three groups, anterior, middle, and posterior, and interposed between two vertical plates of bone; the lateral plate forms part of the orbit, the medial plate forms part of the nasal cavity.
• The nasociliary nerve terminates by bifurcating into the infratrochlear and the anterior ethmoidal nerves.
• The anterior ethmoidal nerve, a branch of the nasociliary nerve, runs in a groove along the lateral edge of the cribriform plate to the above-mentioned slit-like opening.
• The ethmoidal nerves, which arise from the nasociliary nerve, supply the ethmoidal cells; the posterior branch leaves the orbital cavity through the posterior ethmoidal foramen and gives some filaments to the sphenoidal sinus.
• It passes through the anterior ethmoidal canal alongside the anterior ethmoidal artery and vein to emerge in anterior cranial fossa through the anterior ethmoidal foramen (at the junction of the cribiform plate of ethmoid bone and orbital part of frontal bone).
• It is situated superoposteriorly upon the lateral nasal wall, opening into the nasal cavity at the posterior portion of the ethmoidal infundibulum.
• Its medial surface forms part of the lateral wall of the nasal cavity; at its upper part is a rough, uneven area, which articulates with the ethmoid, closing in the anterior ethmoidal cells; below this is an oblique ridge, the ethmoidal crest, the posterior end of which articulates with the middle nasal concha, while the anterior part is termed the agger nasi; the crest forms the upper limit of the atrium of the middle meatus.
• The anterior ethmoidal air cells, and (usually) the frontonasal duct (which drains the frontal sinus) open into the ethmoidal infundibulum.
• Behind the lacrimal process of the inferior nasal conchae lies a broad, thin plate, the ethmoidal process, which ascends to join the uncinate process of the ethmoid; from its lower border a thin lamina, the maxillary process, curves downward and lateralward; it articulates with the maxilla and forms a part of the medial wall of the maxillary sinus.
• Here it gives off its posterior lateral nasal branches which spread forward over the conchæ and meatuses, anastomose with the ethmoidal arteries and the nasal branches of the descending palatine, and assist in supplying the frontal, maxillary, ethmoidal, and sphenoidal sinuses.
